<h2> <a name="headers"></a> API and Extension Header Files </h2>
<p> Because extensions vary from platform to platform and driver to driver,
OpenGL ES segregates headers for each API version into a header for the
core API (OpenGL ES 1.0, 1.1, 2.0, 3.0, 3.1 and 3.2) and a separate
header defining extension interfaces for that core API. These header
files are supplied here for developers and platform vendors. They define
interfaces including enumerants, prototypes, and for platforms
supporting dynamic runtime extension queries, such as Linux and
Microsoft Windows, function pointer typedefs. Please report problems as
in the <a href="index.php#repository">OpenGL-Registry</a> repository.
<p> In addition to the core API and extension headers, there is also an
OpenGL ES version-specific platform header file intended to define
calling conventions and data types specific to a platform. </p>
<p> Almost all of the headers described below depend on a platform header
file common to multiple Khronos APIs called
<tt>&lt;KHR/khrplatform.h&gt;</tt>. </p>
<p> Vendors may include modified versions of any or all of these headers
with their OpenGL ES implementations, but in general only the
platform-specific OpenGL ES and Khronos headers are likely to be
modified by the implementation. This makes it possible for
developers to drop in more recently updated versions of the headers
obtained here, typically when new extensions are supplied
on a platform. </p>
